NON-CONTACT POWER FEEDING SYSTEM, TERMINAL DEVICE, NON-CONTACT POWER FEEDING DEVICE, AND NON-CONTACT POWER FEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To improve heat generation and poorness in efficiency in the case that a transmission power is increased, when a non-contact power feeding system is assembled.SOLUTION: In the case that non-contact power feeding is performed from a power feeding device having a primary coil to a terminal device having a secondary coil, a regulator converting a power received by the secondary coil into a power of a predetermined voltage is made perform a conversion operation in a plurality of systems. A system of a transforming operation performed by the regulator is set on the basis of information obtained by communication between the power feeding device and the terminal device.
